Help="Usage: `basename $0` file [file ...]

Options:
  --help  print this message
  --all   link all files in ./dotfiles

Creates hidden symbolic links for each file in the argument list to ~ (\$HOME)
(i.e., prefaces each name with a '~/.'), saving any existing dotfiles in
./dot_backup.  Subsequent edits can be on eitehr version of the file, but
remember to commit and push your changes periodically.

This was written to be part of the setup when installing the
http://github.com/gltarsa/homedir repo.
